HS 250620 Quartzite

Quick Answer: HS code 250620 specifically covers quartzite, a hard, non-foliated metamorphic rock primarily composed of quartz. This classification includes quartzite in its crude, roughly trimmed, or merely cut by sawing or otherwise, into blocks or slabs of a rectangular (including square) shape. It does not include crushed or powdered quartzite, which falls under other headings. For importers and exporters, the good news is that quartzite under this code generally benefits from a 0.00% ad valorem duty rate in the UK and EU, according to their respective Trade Tariffs and TARIC systems. In the United States, the duty rate is also "Free" across all applicable tariff lines, as per the USITC Harmonized Tariff Schedule. This widespread duty-free status simplifies trade, making it a straightforward commodity to import or export without additional tariff burdens.

How to Classify This HS Code?

What products does HS 250620 cover?

This subheading covers quartzite, which is a hard, non-foliated metamorphic rock that was originally pure quartz sandstone. It is typically white or light-colored, but can occur in various shades of gray, green, or blue due to mineral impurities. The WCO Harmonized System Explanatory Notes for Heading 2506 specify that this heading covers quartz and quartzite, whether crude, roughly trimmed, or merely cut, by sawing or otherwise, into blocks or slabs of a rectangular (including square) shape. The USITC Harmonized Tariff Schedule (HTS) and EU TARIC further define 2506.20.00 as specifically "Quartzite," encompassing the raw material in its various forms prior to further processing beyond basic shaping.

What falls outside HS 250620?

The following products are excluded from HS 250620: quartz, which is classified under HS 250610, even though quartzite is derived from quartz sandstone. Additionally, crushed or broken quartzite, commonly used as concrete aggregates, road metalling, or railway ballast, falls under HS 2517. This distinction is crucial as the processing level changes the classification. Furthermore, articles made from quartzite, such as finished countertops, tiles, or sculptures, are classified in Chapter 68 or other relevant chapters based on their specific function and degree of manufacture, as they are no longer merely raw or roughly shaped stone.

What are common classification mistakes for HS 250620?

A common error is misclassifying quartzite as quartz (HS 250610) due to their close geological relationship and similar mineral composition. Importers must understand that while quartzite originates from quartz, it is a distinct metamorphic rock. Another frequent mistake involves classifying crushed or granulated quartzite under 250620; however, per the WCO Explanatory Notes and General Interpretative Rule (GRI) 1, such products are more appropriately classified under HS 2517 as aggregates. Misinterpreting the level of processing is also common; quartzite that has undergone significant manufacturing beyond simple cutting into blocks or slabs, such as polishing or shaping into specific articles, should not be classified here, as GRI 2(a) and 6 would direct classification to the finished article.

How should importers classify products under HS 250620?

The correct procedure for classifying quartzite involves first confirming the geological identity of the stone as true quartzite, distinct from quartz. Importers and customs brokers should obtain detailed product descriptions, geological reports, or material safety data sheets (MSDS) from suppliers to verify the material's composition and metamorphic origin. Next, assess the level of processing: if the quartzite is crude, roughly trimmed, or merely cut into blocks or slabs, it correctly falls under HS 250620. Any further processing, such as crushing, granulating, or manufacturing into finished articles, necessitates a review of other headings, particularly HS 2517 for aggregates or Chapter 68 for manufactured stone articles, applying GRI 1 and 6 to ensure accurate classification.

FAQ

What are the Most Favored Nation (MFN) import duty rates for quartzite (HS 2506.20) in major markets?

For HS 2506.20 'Quartzite', the MFN (Most Favored Nation) import duty rates are generally very low or free in major trading blocs. For example, the United States (under the Harmonized Tariff Schedule of the United States, HTSUS) applies a 'Free' duty rate for goods classified under 2506.20.00. Similarly, the European Union (EU TARIC) and the United Kingdom (UK Global Tariff) also apply a 0.00% ad valorem duty rate to quartzite. Importers should always verify the specific duty rate applicable at the time of importation via the official tariff databases of the importing country (e.g., USITC HTSUS, EU TARIC, UK Trade Tariff).

Does quartzite (HS 2506.20) qualify for preferential duty treatment under common trade agreements?

Yes, given that the MFN rates for HS 2506.20 are already 'Free' or 0.00% in many major markets, the impact of preferential trade agreements on duty rates for quartzite is often negligible, as there is no duty to reduce further. However, originating quartzite from countries party to free trade agreements (FTAs) with the importing country (e.g., USMCA for the U.S., various EU FTAs) would typically still qualify for duty-free treatment, reinforcing the existing MFN rate. While the duty rate may not change, meeting origin requirements under an FTA can be important for other trade compliance aspects or future tariff changes. Importers should ensure they have valid Certificates of Origin or declarations to substantiate any preferential claims, even if the MFN rate is zero.

What are the key classification criteria for distinguishing quartzite under HS 2506.20 from other similar stone products?

The classification of quartzite under HS 2506.20 is based on its geological definition and composition. Chapter 25 covers 'Salt; sulphur; earths and stone; plastering materials, lime and cement.' Heading 2506 specifically covers 'Quartz (other than natural sands); quartzite, whether or not roughly trimmed or merely cut, by sawing or otherwise, into blocks or slabs of a rectangular (including square) shape.' The key distinction for quartzite is its metamorphic origin and high silica content, primarily composed of quartz. It must be differentiated from sandstone (which is sedimentary) or other siliceous stones. The WCO Explanatory Notes for Heading 2506 provide further guidance, clarifying that quartzite is a compact, granular, metamorphic rock consisting essentially of quartz, often derived from sandstone. Importers should be prepared to provide geological descriptions or analyses if requested by customs authorities to support the classification.

Are there any specific documentation requirements or import restrictions for quartzite (HS 2506.20)?

Generally, quartzite (HS 2506.20) is considered a basic mineral commodity and does not typically face specific import restrictions or require special permits beyond standard customs documentation. Importers will need the usual commercial invoice, packing list, bill of lading or air waybill, and potentially a certificate of origin, especially if claiming preferential treatment under a trade agreement. While not common, some countries may have specific regulations concerning radioactive materials or other hazardous substances that could potentially be present in trace amounts in natural stone, though this is rare for quartzite. It is always prudent for importers to check the specific import regulations of the destination country and any relevant environmental or health and safety standards that might apply to bulk mineral imports.
